I have a Y2000 MV6 - 3 litre. I think I have an immobiliser problem, because sometimes the car won't start, but will if I lock and unlock. I think I've ruled out key problems because I have two keys, both with replaced batteries and the problem occurs with both.
I think I may be heading for trouble - does anyone have experience of this or suggestions?

Immobiliser chip in the keyfob doesn't need any battery power.

Does the ecu light flash (indicating an immobiliser problem) when it happens?

Thanks for this, I understand the first part - useful info.

At the point that the engine is turning but not starting, all the dash warning lights are on - they only blow out when the engine starts. Or did I missunderstand the question, is there another light somewhere?

Soudns more like crank sensor to me......if it was immobiliser stopping the engine firing the ECU light would flash.

Let me get this straight - it would flash instead of being on steadily? Its intermittent so I haven't had the chance to look for this yet.

If the ecu light is on steadily, then it's indicating a fault with the ecu or sensors somewhere.

If the ecu light is flashing when you first turn the key, then it's indicating that there is a problem with the immobiliser, and the engine will not start.
